A Better SQL in 11 Lines of Code

UCLA's RePL lab introduces Prela, a query language built on binary relations. This tutorial shows how to implement a toy version in Python, revealing that complex SQL joins can be expressed as simple relation compositions. By decomposing tables into two-column relations and using operators like `.select`, `&`, and `.where`, Prela composes queries that read like natural language. The result: a 20-line SQL query becomes an 11-line Prela expression, with the added benefit of composability and clarity.
